Product Overview
The ATC-HHMMSS-T Industrial LED Wall Clock is a professional time display solution designed for factories, warehouses, hospitals, schools, offices, and industrial facilities requiring accurate and highly visible time synchronization.
Featuring a large 6-digit HH:MM:SS display, high-brightness 7-segment LEDs, and industrial-grade construction, the clock delivers clear visibility from long distances while ensuring stable operation in demanding environments. Designed and manufactured by ATPro, the system can also be customized with OEM options including communication interfaces, LED colors, housing materials, and display sizes.

Application
The ATC-HHMMSS-T Industrial LED Wall Clock is widely used for:
-
Office buildings and meeting rooms
-
Manufacturing facilities and production lines
-
Warehouses and logistics centers
-
Cold storage facilities
-
Hospitals and medical centers
-
Educational institutions
-
Shopping malls and public buildings
-
SCADA, MES, and Andon systems
-
Industrial automation projects
• Facilities requiring both time synchronization and environmental monitoring can also deploy Temperature Humidity Date Time Display solutions
The Problem
Many organizations face challenges when using conventional wall clocks in large facilities.
Common issues include:
-
Small clock displays that are difficult to read from a distance
-
Poor visibility under strong lighting conditions
-
Limited durability in industrial environments
-
High costs associated with imported display systems
-
Lack of synchronization between departments and production areas
-
Difficulty integrating time displays into existing SCADA or MES systems
These challenges can reduce productivity, affect operational coordination, and create inefficiencies in daily activities.
The Solution
The ATC-HHMMSS-T Industrial LED Wall Clock provides a reliable and cost-effective solution for professional time display applications.
With large LED digits, industrial-grade electronics, and high-accuracy RTC technology, the clock ensures consistent time synchronization across production facilities, warehouses, hospitals, schools, and commercial buildings.
The flexible OEM design also enables customization for specific project requirements, including communication interfaces, branding, display size, and additional functionality.
